Release Notes: When pen writes its configuration file, weight information is now included. Weight-based server selection now works better for small numbers of connections.
Release Notes: Server weight can now be specified on the command line and displayed using the penctl command. Installation instructions for Windows were updated. A sanity check was added to the initialization code.
Release Notes: This release fixes a bug in the weighted server selection: server_by_weight would never consider blacklisted servers, which kept them blacklisted indefinitely.
